ТЕЛЕГОНИЯ (влияние первого самца) - ТОП-7 молекулярных аспектов передачи ДНК от первого партнёра

In fact, modern scientists know much more about telegony than people think. However, they use a completely different term: "non-Mendelian inheritance." It has only recently become possible to study this phenomenon. And only with the development of molecular methods. It is generally accepted that sexual intercourse is a means of delivering sperm to (and into) the egg. If fertilization succeeds, great; if not, then nothing happened. However, this model is greatly simplified. Firstly, semen contains many more sperm than necessary for fertilization, and secondly, it consists of almost 70% seminal fluid. Sperm, like all cells in our body, release fragments of their DNA into the environment—so-called extracellular DNA. Unlike regular DNA, which is found in the nucleus and mitochondria, extracellular DNA, as the name suggests, is found outside cells, in tissues. Another difference: Genomic DNA consists of long strands called chromosomes, while extracellular DNA is a collection of small sequences, sometimes a million times shorter than chromosomes. In many ways, extracellular DNA remains a huge mystery to science, but there is already evidence that animal and human cells can absorb such DNA from the blood. In some cases, these molecules reach the cell nucleus, penetrate, and integrate into the cell's own genome. __ Follow kRAMola on social media: VK https://vk.com/ OK https://ok.ru/ Telegram https://t-do.ru/ Instagram https://www.instagram.com// Website http://www. #telegony #DNA Zen https://zen.yandex.ru/kramola
